Former SpaceX employee Josh Boehm told Business Insider
that interviewing with the company is intense.

There are seven to eight face-to-face
interviews.

At any point in the process, if even one person doesn't
like the candidate, the interview stops and the applicant is
sent home.

It's well established that working for Elon Musk at SpaceX can be intense.

But the grueling culture begins even earlier than on the first
day of work, according to former SpaceX employee Josh Boehm, who
described the "gauntlet that is the SpaceX interview process" to
Business Insider.

There "was a very strict hiring policy," Boehm, now
cofounder and COO of Cyph, said. "Elon and Gwynne
[Shotwell] from the top down said we only really want top talent
coming in. It was really difficult to bring people in and get
them on the team."

Here's what the interview process entailed, according to Boehm,
who worked at the company form 2013 - 2016:

Teams in HR pore over piles of resumes.

Then applicants have two to four phone screenings to see if
they are qualified for in-person interviews.

Candidates who make it through those four phone conversations
are brought to the SpaceX campus for a full day of interviewing
with "everyone who might work with them."

Interviewers talk to candidates in pairs where they are
"grilled" in seven to eight one-hour interview sessions.

Halfway through, they get a break for lunch and to take a
tour of factory. The second half of interviews then
commence.

If even one person expresses doubt at any part in the
process, the interview comes to a halt and the applicant is
immediately sent home.
